In this work, high-quality lithium-based, LiYF4=Yb3+,Er3+ upconversion (UC) thin film was electrodeposited on fluorene-doped tin oxide (FTO) glass for solar cell applications. A complete perovskite solar cell (PSC) was fabricated on top of the FTO glass coated with UC thin film and named (UC-PSC device). The fabricated UC-PSC device demonstrated a higher power conversion efficiency (PCE) of 19.1%, an additional photocurrent, and a better fill factor (FF) of 76% in comparison to the pristine PSC device (PCE = ~16.57%; FF = 71%). Furthermore, the photovoltaic performance of the UC-PSC device was then tested under concentrated sunlight with a power conversion efficiency (PCE) of 24% without cooling system complexity. The reported results open the door toward efficient PSCs for renewable and green energy applications.
在这项工作中，高质量的锂基LiYF4=Yb3+、Er3+上转换（UC）薄膜被电沉积在氟掺杂氧化锡（FTO）玻璃上，用于太阳能电池应用。在涂有UC薄膜的FTO玻璃顶部制备了完整的钙钛矿太阳能电池（PSC），并命名为（UC-PSC器件）。与原始PSC器件（PCE = ~16.57%；FF = 71%）相比，制备的UC-PSC器件表现出更高的功率转换效率（PCE），为19.1%，额外的光电流以及更好的填充因子（FF），为76%。此外，UC-PSC器件的光伏性能随后在聚光阳光下进行测试，在没有复杂冷却系统的情况下功率转换效率（PCE）为24%。所报道的结果为可再生和绿色能源应用中的高效PSC打开了大门。
